RTS UIO-256 (01) PDF Document

The RTS UIO-256 shipping box should contain the following items:

• 1 UIO-256 System

• 1 Power Cord (110V or 220V)

• 2 50-pin Telco Connector (no cable)

• 1 User Manual

• 1 Serial Cable

• 1 Warranty Card

Each RTS UIO-256 provides 16 GPI inputs and 16 GPI outputs. The GPI inputs can be set up as remotely controlled keypanel keys to activate intercom ports, party lines, GPI outputs, etc. within the intercom system. The GPI outputs are typically assigned for activation from keypanel keys and can be used to control lighting or to key remote transmitters, paging systems, etc.

The RTS UIO-256 exchanges control signals with the intercom system via an RS-485 data connection. Multiple UIO-256 units may also be interconnected using a multi-drop configuration (requires version 2 of the UIO-256 firmware).

GPI inputs are connected via a 50-pin telco connector on the back of the unit. Each input requires +5 to +18 VDC for activation. The positive input and common connections can be provided from a remote source, or the UIO-256 can supply +18 VDC at the connector for input activation with a user-supplied external switch.

For systems with firmware 9.2.1 or newer, the RTS UIO-256 must be configured to work in Multi-Drop mode. Set DIP switch 1-2 to the CLOSED position. Up to 16 UIO-256 frames can be connected together in this configuration.

For systems with firmware older than 9.2.1, the RTS UIO-256 must be configured to work in Token Ring mode. Set DIP switch 1-2 to the OPEN position. Up to four UIO-256 frames can be connected together in this configuration.

Only the SW1 bank of DIP switches is currently used. Their functions are as follows:

• SW1-1: Diagnostics mode. Leave in the OPEN position for normal operation. If open, GPI outputs operate normally. If closed, GPI outputs will track the corresponding GPI inputs.

• SW1-2: Communications Mode. Open = Token Ring; Closed = Multi-Drop (default).

• SW1-3: Unused. Leave in the OPEN position.

• SW1-4 to SW1-7: Frame number. These switches set the frame number for the unit.

• SW1-8: Baud rate. This must be closed for communication with the intercom system (76.8K baud).

NOTE: Frame numbers 5-16 are possible only when using multi-drop mode.

RTS UIO-256 frames are generally mounted in the front of an equipment rack near a Master Controller Breakout Panel for ADAM intercom systems or near the matrix frame for ADAM CS intercom systems. When positioning the unit, consider the visibility of the front panel status indicators and access to the reset switch. Also, consider access to the rear panel for fuse replacement or changes to the DIP switch settings. There are no ventilation requirements.

Connect the end of the 9-pin cable marked “ADAM System” to J3 of the XCP-ADAM-MC Master Controller Breakout Panel. Connect the end marked “UIO-256” to J2 of the UIO-256 Frame.

For ADAM CS systems, the connector marked “ADAM System” on the 9-pin cable must be replaced with the provided female connector. Disconnect the wires and reconnect them to the same pin numbers.

After modifying the cable, connect the newly attached female connector to J902 of the ADAM CS frame. Connect the end marked “UIO-256” to J2 of the UIO-256 frame.

To connect more than one RTS UIO-256 frame, or to connect a Program Assign Panel, you must construct a “Y” cable. This cable replaces the supplied 9-pin cable. It will have additional DB-9S connectors in parallel with the main ADAM or ADAM CS connector. Connect the additional connectors to the J2 connector on each additional UIO-256.

The Zeus system is compatible only with RTS UIO-256 firmware Version 2 or later and only supports a multi-drop connection.

1. Use the DIP switch settings for ADAM and ADAM CS systems. Ensure DIP switch 2 is set to CLOSED for “multi-drop” connection.

2. Zeus is limited to 64 GPI inputs and 64 GPI outputs, which means you can use a maximum of four UIO-256 frames. Only frame numbers 1 through 4 are allowed.

3. Treat the Zeus system the same as an ADAM system for wiring, but connect to J26 on the Zeus back panel instead of J3 of the XCP-ADAM-MC breakout panel.

Use 50-pin Telco cables to connect from the GPI input and output connectors on the RTS UIO-256 to punch blocks or similar breakout devices.

1. Assign GPI inputs by using the GPI Inputs setup screen, which is accessible by clicking the GPI Inputs button on the AZedit toolbar.

2. Assign GPI outputs using the GPI Outputs setup screen, which is accessible via the GPI Out button on the toolbar.

NOTE: AZedit requires the number of GPI Ins and GPI Outs to be set throughout the Intercom Configuration menu (select Options > Intercom Configuration). This will require the unit to be reset, and all data will be lost. Be sure to save your setup before reconfiguring the frame.

Yes, on keypanels that permit key assignment, you can assign GPI outputs using the procedures for assigning relays. It is not possible to assign GPI inputs from keypanels.

• OUTPUT STATUS: Activating a keypanel key that is assigned to a GPI output will cause the appropriate OUTPUT STATUS indicator on the UIO-256 front panel to light, and the relay contact for that output will activate.

• INPUT STATUS: Activating a GPI input from an external device will cause the appropriate INPUT STATUS indicator to light, and the keypanel key assignment or other device within the intercom system that is assigned to that GPI input will activate.

When using multiple UIO-256 frames, the status indicators on the first UIO-256 will show the status of the first 16 GPI outputs and inputs. The indicators on the second UIO-256 will show the status of outputs and inputs 17 to 32, and so on.

The RTS UIO-256 firmware is designed to detect and recover from errors like lost or bad data packets. However, in the unlikely event the unit stops functioning, you can try pressing the reset switch on the front panel of the UIO-256.

The fuse is accessible on the rear panel power module. To replace it:

1. Remove the power cord from the power module.

2. Free the fuse cartridge from the module.

3. Replace the fuse with a new fuse of the same rating and type.
